The Death Master File (DMF) from the Social Security Administration (SSA) currently contains over 94 million records. The file is created from internal SSA records of deceased persons possessing social security numbers and whose deaths were reported to the SSA. Often this was done in connection with filing for death benefits by a family member, an attorney, a mortuary, etc. Each update of the DMF includes corrections to old data as well as additional names. [NOTE: If someone is missing from the list, it may be that the benefit was never requested, an error was made on the form requesting the benefit, or an error was made when entering the information into the SSDI.] Beginning in 2014, legislative rules governing the SSDI changed. Going forward, records from the most recent 3 year period will not be available to Ancestry.com. Once a record is made available, it can be published.
